" IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 150,340, dated April 28, 1874; application filed March 23, 1874.

To all whom t may concern: y,

Be it known that '1, DANIEL E. MGSHEREY, of Dayton, in the county of Montgomery and State of Ohio, have invented certain Improvements in Grain-Drills, of which the following is a specication:

My invention relates to grain drills; and consists in a novel manner of attaching the receivers or grain-conductors to the feed-cups, as hereinafter more fully explained, the device being an improvement on those patented by me January 24, 1871, numbered 111,132, and July 18, 1871, numbered 117,191. y

Figure 1 is a side view of my improved device, showing the receiver or grain-conductor attached to the feed-cup, the form of said cup being shown in dotted lines. Fig. 2 is a face view, a portion-being brokenaway to show more clearly the operation of the parts.

rlhe receivers or grain-conductors are made detachable, in order that they may be so placed as to cause the machine to deliver either forward or in rear of the feed-cups.

In the patents above referred to the receivers or grain-conductors were attached to the feed-cups by means of hooks locking' over the top of the driving-shaft, the said hooks being held over the shaft by means of springs. It has been found in practice, however, that this arrangement caused friction and consequent wearing away of the drivin g-shaft.

To obviate this difficulty is the object of my present invention.

In the drawing, B represents the bottom of the seed boX or hopper, to which is attached the feed-cup A. This cup A is provided at its lower end with lugs or ears O projecting downward, there being one on each side of the cup. These lugs or cars are provided with a hole or opening, through which the end of a hook, O, passes, the said hook being connected to the receiver or grain conductor E, thus locking the receiver to the feed-cup A.

In order to prevent the hooks O from workA ing out, and thus allowing the receiverl to become detached from the feed-cup, I provide springs s, one end of which f1t over projections a cast on the receiver or grain-conductor, and the other in recesses formed in the lower ends of the hooks O, as shown in Fig. 2. The hooks O being pivoted at l the upper ends are thrown inward by the pressure ofthe springs s at the lower end, thus making the attachment of the receiver to the feed-cup secure and rigid, while the upper portions of the receiver or grain conductor resting against the upper part of the feed-cup A prevent any rattling of the receivers, and hold the same in the proper position.

It will be observed that, by this arrange-I ment, the unnecessary wear and friction on the dri ving-shaft D are avoided, and the attachment of the receiver to the feedcup made even more secure than' by my former device, while at the same time the receivers or grain-conductors .may be readily detached and reversed. 1

It will also be observed that the arrangement of the hooks permits them to be readily operated by one hand, whereas the device shown in my patents, above referred to, re'

quired the use of both hands, and was, conse'
